I have had my car for six months now, first car purchase so price was essential in getting the loan. I know it would be better to start with a better base platform and that this can end up costing me more money in the long run than getting an M, but it is the route I am choosing to go. Plus I love my four doors.

I ordered the Twin Screw kit last Friday and purchased everything I need for the manual swap today. Catless headers and custom 2.5" pipes will be in the next few weeks. M3 subframe swap or sticking with the 3.46 and getting a LSD is the only thing I am on the fence about. Depends if I can handle the cruising RPM with 5 speed.

This post is just the beginning of the transformation from a nice car (I think) into a decently quick car that will hold it's own. I will include many photos along the way and hopefully it works out well.

Thoughts, input and criticism welcome. Excuse the long post.
